Description

In trying to update to Rails 7.1 I'm running into random instances of this error when running my test suite.

Error:
Jsonapi::V1::TeamProjectsControllerTest#test_should_not_create_for_a_forbidden_team:
NameError: uninitialized constant JSONAPI::ResourceController
    app/controllers/jsonapi/v1/base_controller.rb:3:in `<main>'
    app/controllers/jsonapi/v1/team_projects_controller.rb:1:in `<main>'
    test/controllers/jsonapi/v1/team_projects_controller_test.rb:126:in `block in <class:TeamProjectsControllerTest>'

Sometimes there will be 2 of them, other times 20 or 30.

Via some trial and error I discovered that if I alter my BaseController to look like this:

class Jsonapi::V1::BaseController < ActionController::Base
  include JSONAPI::ActsAsResourceController
  # ...
end

Instead of this:

class Jsonapi::V1::BaseController < JSONAPI::ResourceController
  # ...
end

then the random errors go away.

I also noticed that these errors were only happening locally, and not in CI, and so I tried setting config.eager_load = true in config/environments/test.rb which also made the errors go away.

I poked around this gem a little bit and I think that this block of code isn't exactly working as expected in Rail 7.1.

jsonapi-resources/lib/jsonapi-resources.rb

Lines 12 to 18 in e92afc6

	if Rails::VERSION::MAJOR >= 6
	ActiveSupport.on_load(:action_controller_base) do
	require 'jsonapi/resource_controller'
	end
	else
	require 'jsonapi/resource_controller'
	end

Ruby: 3.3.6
Rails: 7.1.5.1

For anyone else that runs across this it's worth mentioning that another possible app-side fix is manually requiring ResourceController before using it.

require 'jsonapi/resource_controller'

class Jsonapi::V1::BaseController < JSONAPI::ResourceController
  # ...
end
